Precipitation Hardening Grades. Precipitation hardening stainless steel, like the martensitic types, can be strengthened and hardened by heat treatment. Both martensitic or austenitic precipitation hardening structures can be produced.Precipitation Hardening Stainless Steels | Stainless Steel hardenable stainless steel gradesPH Stainless Steel Grades. Precipitation Hardening (PH) stainless steels are classified as martensitic or semi-austenitic. They develop their high strength and hardness through a variety of heat treatments resulting in a very high strength-to-weight ratio. Semi-austenitic grades are 17-7 PH ® and PH 15-7 Mo ®. They are austenitic in the annealed state, and martensitic in the hardened condition.400 Series Stainless Steel - Penn Stainless Products hardenable stainless steel grades400 Series Stainless The 400 series group of stainless steels has an 11 percent chromium and 1-percent manganese increase, above the 300 series group. The 400 series is susceptible to rust and corrosion under some conditions. Heat-treating will harden the 400 series.

These steels are the most popular grades of stainless produced due to their excellent formability and corrosion resistance. All austenitic steels are nonmagnetic in the annealed condition. Depending on the composition, some austenitics do become somewhat magnetic when cold worked.
Aug 22, 2016 · When welding austenitic stainless steels, grades such as 304L or 347 should be used. Grade 304L has lower carbon while 347 has niobium stabilizers added to it which help to deter intergranular corrosion. Ferritic stainless steels such as grade 430 or grade 439 are also readily weldable, as are Duplex stainless steels.Martensitic stainless steel and precipitation hardening hardenable stainless steel gradesMartensitic stainless steel grades are basically Fe-Cr alloys with a higher carbon content than ferritics which enables them to harden on cooling in air, oil or water. Depending on grade and intended use, ductility is improved by tempering.Precipitation Hardening Stainless Steels - TWIThe precipitation hardening (PH) stainless steels are a family of corrosion resistant alloys some of which can be heat treated to provide tensile strengths of 850MPa to 1700MPa and yield strengths of 520MPA to over 1500MPa - some three or four times that of an austenitic
Hardenable Carbon Steels. Abstract: Carbon steels are produced in greater tonnage and have wider use than any other metal because of their versatility and low cost.
